Messing with old junk is sometimes amazingly cool. I wanted to build enclosures for some Philips car audio full range speakers that are from the mid or late 80ies. They're 13 cm speakers and sport 25 Watts max and 92 db.
I had some old boxes containing a 8 cm tweeter and a 8 cm mid band speaker. The mid bands were shot. I soldered them out and also took out the XO that was just a copper wire on a roll. Yay! Free copper wire for me! 😀 The tweeters were XOed by a bipolar caps. Eewww.
Anyways, out of curiousity I just soldered in the Philips speakers instead of the 8 cm speakers and connected the tweeters also, retaining the cap. As the 8 cm hole is obviouls too small for the 13 cm speakers to fit, I just screwed them in place by 2 screws. You can still see the back part of the membrane...
What can I say. The tweeters give them a remarkable clarity wich the full rangers are definately missing. Although it's a quick and messy hack job, those boxes produce an incredible warm bass for their size. I will refine their design and use them together with a subwoofer. Junk rules! 😀
